Halfway Between 89 and 518

When you ask "What number is halfway between 89 and 518?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=89 and Y=518.

Halfway Between Line

To find the number halfway between 89 and 518, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 89 and 518 into our formula, we get:

(89 + 518)/2 = 303.5

Thus, the number halfway between 89 and 518 is 303.5.

To check that our answer is correct, we subtract 89 from 303.5 and subtract 303.5 from 518 and compare the two numbers:

303.5 - 89 = 214.5
518 - 303.5 = 214.5

As you can see, the halfway number is 214.5 higher than 89 and 214.5 lower than 518. Therefore, our halfway between answer of 303.5 above is correct.
